: The system accounts for complex factors like terrain elevation (using DTED data), air temperature, and humidity.

: A highly useful post/paper for understanding the system's "guts" is AREPS and TEMPER – Getting Familiar with these Powerful Propagation Software Tools. It compares AREPS with other models and explains its use of the "Parabolic Equation" method for calculating wave propagation. Areps Free

: It calculates the probability of a radar detecting a target based on height, range, and bearing. : The system accounts for complex factors like

: The AREPS Version 1.0 User Manual is available via DTIC. It documents the software’s interface, which was designed to be user-friendly with Windows-based menus and "drag and drop" features. : It calculates the probability of a radar

: For those wondering how to obtain the software, the Defense Systems Information Analysis Center (DSIAC) provides a technical inquiry service where you can request information on accessing AREPS for research or official use.

: A more recent study (2020) on Analysis of Target Detection Performance discusses how AREPS is used to model abnormal atmospheric conditions like "ducts" that can trap radar signals and extend their range. What AREPS Actually Does
